-f AUTOMOBILE BUMPER.

Application led January 13, 1927. Serial No. 160,888.

i This invention relates to improvements in automobile bumpers, and itsobjects are to provide a bumper which will withstand orlo a bumper ofthe character set forth which' will utilize the resilienc lof the air.in cushf ioning shocks and jars t at may be sustained by the automobile.Y 1

The drawings delineate preferred embodiments merely, and it is to beunderstood that changes and minor alterations, properly falliiig withinthe scope of the appended claims, may be made without departing from thespirit of the invention. A

In the drawings, Figure 1 is a top plan view of a bumper constructed inaccordance with my invention, Fig. 2 is a sectional view of the bumpertaken on line X12-XL., of Fig. 1. Fig. 3 is a fragmentary'view of thecushioning fabric showing the inner side of the end cut away. Fig. 4 isa rear elevation of an automobile with the bumper applied thereto. Fig.5 is a top plan view of the bumper adapted to be applied on the front ofthe automobile. Fig. V6 is a front elevation of an automobile with thebumper applied thereto.

Referring to the drawings, the bumper embodying the present inventionhas an outer clamping member 11, and an inner clamping member 12. Theouter clamping member has a flange 13 adapted to project over the top ofthe inner clamping member. The inner clamping member has a flange 14, towhich are attached the supporting brackets 15, which are adapted to besecured to the automobile at the preferred location. To force the clampmembers together, I provide drawA bolts 16, projecting from theouter'clamp v member, and nuts 17, therefor, on the inner face of theinner clamp member.

To cushion shocks and jars, I provide a collapsible tube 18, of fabric,such as heavy canvas fabric, which is mounted on the outer face of theouter clamp member. The ends of tube 18, are cut away with a notch 19,on the inner side thereof. This allows the ends of the tube to beflattened and inserted between the extremities 20 and 2l, of the clampmembers. Within tube 18, I provide a collapsible and inflatable rubbertube 22, whichk is provided with an air valve23, for inflation thereof.

In use, the inner tubes are inflated, thereby i providing an eflicientcushioning element for the bumper. Y, v

The bumpers may be of the forni shown in Fig. l, whichis particularlyadapted to bev secured to and project from the endof each ,vehiclespring, or may be of the form shown in Fig. 5, which extends completelyacross the front or rear of the automobile.

By providing means for constricting the ends of the outer fabric member,the same,

may be of larger dimensions than the clamp members, as shown.

From the foregoing description and draw- I ings, it may be seen that Ihave provided an improved bumper which is inexpensive to construct, isreadily applied for use, and

which will eniciently withstand the ordinary shocks and jars incident toordinary use.

What is claimed is: 1. In an automobile bumper, outer and inner clampmembers, supporting brackets extending from the inner clamp member,

means for drawing the clamp members together, a flexible fabric tubemounted on the outer faceof the outer clamp member and having itsextremities inserted between the clamp members, and an inflatable tubevmounted within the flexible fabrictube.

2. In an automobile bumper, the combination with outer' and inner clampmembers and means for drawing the clampmembers together, of supportingmeans extending from the inner clamp member, a iexible fabrictube'mounted on the louter face of the outerV clamp member, and havingits extremities capable of constriction for insertion between the clampmembers, and an` inflat-able member disposed in the fabric tube.

3. In an automobile bumper, the combination with outer and inner clampmembers and means for drawing the clamp members together, of lsupporting means extending from the inner clampmember and adapted `to besecured to the automobile, a flexible fabric tube mounted on the outerface of the outer clamp member, and having its extremities insertedbetween the'clalmp members, lan

inflatable tube within the fabric tube, and
